ALSO POSTED THIS IN THE SPECIAL OFFERS FORUM,but wasnt sure everyone looked in there taken from www.thedvdforums.com The best price I've found is Amazon. 5 x Verbatim 4.7Gb in cartridge £5.29 http://www.amazon.co.uk/exec/obidos...rums-21&path=tg 5 x Verbatim 9.4Gb in cartridge £6.76 http://www.amazon.co.uk/exec/obidos...rums-21&path=tg I've bought a stack of each - the price was so good. And they work perfectly with the E55. They also sell them without the cartridges (£3.94 for 5 single sided). I think they're having some stock problems (some of mine took 3-4 weeks) but all have eventually arrived and I've been billed the advertised price.
